The intraweb suggests that 5nm is what's needed.
Thought I'd check how tight I tighten my bolts to. It's 8nm , is that too tight?
Tried tightening to 5nm but I could still twist my bars.
What do the manufacturers of your bars and stem say?
All mine seem to be 5 or 6nm.
5mm is pretty standard with stems with M5 bolts, stems with M6 bolts usually a bit higher, I've seen 8nm stated on some old stems, if my bars were carbon I'd be sceptical about going that high though. Find a similar spec stem to yours and look up that stems torque settings if you can't find them for your stem.
Hope AM stem is 6-7Nm
All my stems with m5 bolts using a 4mm allen key say 5nm for the face plate, an old truvativ stem I've got with m6 bolts says max 6.8nm.
Is your torque wrench accurate at those low levels? 5nm should be plenty to hold the bars in place. I bet mine are not even that tight
It depends, my Thomson one is about 4nm whereas my RaceFace one says up to 9nm. I use friction paste so less torque is needed.
Ideally you tighten as little as possible for it to do its job
TJ ,I've got one of these

Hmmm - no name torque wrench . I wouldn't trust it to be accurate enough. Maybe my bias against the seller showing of course but 5nm should be plenty tight enough for stem faceplate bolts IMO
I would forget the torque wrench and do them up with a standard allen key just a tweak past finger tight using the long end
I alway do mine up 6nm
Something is seriously wrong if you can move your bar at 5Nm, unless you are rocking Ape Hangers!
It's all nonsense without knowing the size of the fastener - 5Nm on an M5 =/ 5Nm on a M6. Are the threads greased or loctited?
A M6, ungreased bolt at 5Nm could exert less than half the load of an M4 that's been greased at 5Nm.
Torque it to the manufacturer spec, and assemble it with/without grease as they tell you.
I had carbon bars turn in a Thomson stem I torqued up using a bontrager 5nm dedicated doodah (bought for carbon seat post when I dabbled as roadie scum). Which is why I sold the bars...
Only 10mm risers too...
Never had problems using the same thing on Hope stems I’ve on pretty much everything now... but with alu bars I don’t mind a little extra tighten if it doesn’t feel up to snuff...
